Christmas Bird Count statistics
By Dick Hoffman
Many years ago, my wife Jean & I began a project involving the Cleveland region Christmas Bird counts. We collected data for each year starting with the one conducted in 1940 and built up a database of each year's observations. We then computed reports by year for the current year and also one with statistics from data in the accumulated database. The reports were computed using COBOL programs run on our employer's mainframe computers until we got a home PC and converted the database to fit on it and rewrote the programs in BASIC.
Later I converted the database to OpenOffice Base when Microsoft dropped Visual Basic V3 Examples of these reports are attached. Presented below are the reports for the count conducted last December and the statistics report for data through the 2018 count. The reports are written in HTML because after creating them we posted them on a webpage that we maintained. Our web page went away several years ago due to our ISP dropping support for user web pages but I continued to update the database and run the reports every winter.
